Turns out, the problem was that I was almost out of disk space. Well, not really. I have 9 GB of disk space at [Dreamhost](http://www.dreamhost.com/rewards.cgi?momathome) to use across 15 domains. Most of the sites I host take barely 100 MB of space. I have more than enough room and then some. The problem is that I didn’t realize that my login had a hard limit set of only 300MB and I was using 99.9% of that. That’s all there was to it. On rebuild, Movable Type writes to a temporary file and I’m assuming that the rebuild process was pushing it over the limit and therefore wasn’t completing.

I had an email this morning telling me that I was out of disk space for my login (thank goodness it’s a Sunday so I doubt I missed any important mail). One click in the control panel to give my login more breathing room and the problem is fixed. I rebuilt the category archives and they look fine now.

So for Googlers: If you find that you are not getting complete pages upon rebuilding your Movable Type blog check your server disk space. That may very well be the problem.

And [Eric](http://www.outofcheese.org), I’ll go and put the comment and trackback counts back in my RSS feed now. I’m sure the wackiness I was seeing was due to the above problem.
